The Salvage pit quest door doesn't seem to lead anywhere still.
Also neither the old trog quest, nor the old Hoar quest bubble works so I'd assume it will be the same with volts as well.
Thanks for the report, but please don't make assumptions - I'd really a confirmation about the Volt quest.
The Portal to the surface quest drops a key, but the key does not open the last door, only a high locksmith attempt does. This, as the only exit, needs to be corrected.
Volt quest works.
Not sure what troglodyte quest you're referencing as none exist (can you say where the quest bubble is?). The other bugs should be fixed v101 hopefully.
It's the one hrunpar gives, the duerger by dark (?) lake.
Ah... old dialogue. Fixed.
